GUSTAV J. LANGE, OF EAU CLAIRE, WISCONSIN.

SEPARATING DEVICE.

To all whom it may concern:

Be itknown that I, GUSTAV J. LANGE, a citizen of the United States, residing at Eau Claire, in the county of Eau Claire and State of IVisconsin, have invented certain new and usefulImprovements in Separat ing Devices, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to new and useful improvements in separating devices and more particularly to a device known as a bean separator, and my object is to provide a. device of this character which will positively separate the product from the hulls and other extraneous matter.

A further object of the invention resides in providing a device known as a floater wherein the hulls and other extraneous matter adapted to be separated from the procluct will be floated in fresh water above the product proper and a further object of the invention resides in providing a spiral screw in the member receiving the product to convey the product which is adapted to be separated from the remaining properties to a predetermined place.

Still another object of the invention resides in providing a device which is eX- tremely simple and durable in construction, inexpensive to manufacture and one which will be very eflicient and useful in operation.

lVith these and other objects in view, the invention consists in the novel features of construction, combination and arrangement of parts as will be hereinafter referred to and more particularly pointed out in the specification and claim.

In the accompanying drawing forming a part of this application, Figure 1 is a side elevation of the device partly in section; Fig. 2 is a top plan view thereof; Fig. 3 is a transverse section through the same, as seen on line 33, Fig. 2; and Fig. at is an end elevation of the device.

In describing my invention, I shall refer to the drawing in which similar reference characters designate corresponding parts throughout the several views, and in which 1 indicates a trough or the like mounted upon the supporting legs 2, the bottom of said trough 1 being provided with a groove or channel 3 extending through the longitudinal center thereof and the inner face of Specification of Letters Patent.

Serial No. 682,590.

said bottom being inclined outwardly from said groove to the side edges of said bottom as shown at 4. Said bottom is also inclined upwardly from one end of the trough to the other and disposed in the groove or channel 3 is a spiral screw 5, the same being carried on a shaft 6 which is rotatably mounted in said trough. The one end of said shaft 6 is secured to an additional shaft 7 by means of a knuckle 8, said additional shaft 7 hav- 111g mounted thereon a pulley 9 which connects with any desired source of power, not shown, and it will thus be seen that the spiral screw 5 may be caused to rotate within the trough to cause the matter therein to be conveyed toward the upper end thereof.

Mounted on the trough at the upper end thereof is a spout or the like 10 over which is mounted a screen 11, said spout having communication with the groove or channel 3 in the bottom of said trough so that all matters conveyed to this portion of the spout, by means of the screw 5, will be conducted to the spout and the opposite end of said trough 1 has mounted therein, adjacent the upper portion of the same, a spout 12, the purpose of which will be hereinafter more particularly described.

Extending transversely of the trough 1 about midway of its ends, is a perforated pipe section 13 which connects with a water supply pipe 1 1 and extending from the bottom of said trough at the lower end thereof is a drain pipe 15.

In practice, a product such as beans together with the hulls which have been previously removed therefrom, are emptied into the trough 1 between the pipe 13 and the lower end of the same, it being understood that said trough has been filled to overflowing with water from the pipe 14. The hulls and other extraneous matter will float upon the top surface of the stream of water which is continually flowing downwardly and through the overflow spout 12, while the product, in this instance, beans, will drop to the bottom of the trough to be conveyed to the channel or groove 3. The spiral screw 5 within the channel or groove 3 being rotated, will cause this product within the groove to be conveyed toward the upper end of the trough and emptied into the spout 10, while the lighter hulls and the like will be conveyed by the flowing stream of water through the overflow spout 12. The product having been emptied upon the screening 11 ot the discharge spout 10 may be conveyed to any other form of device such as the lilli g machine, while the hulls and other extraneous matter which are caused to be discharged. to the overflow will be caught in a receptacle 16 at the opposite end of the trough. Thus it will be seen that it is only necessary to empty the product with the hulls into the trough and the separation of the product from said hulls will be autoni a t ic.

ll hile l have described this device as be ing particularly used in connection with the separation oi? hulls from beans, it will be a 'ipreciated that the Seine may be used for the separation of extraneous matters from various other products.

From the foregoing, it will be seen that l hare provided an improved separating device which is extremely simple and durable in construction, ineiqoensire to manufacture and one which will be very ellicient and useful in operation.

While I have particularly described the elements most well adapted to perform the functions set forth, it is obvious that various changes in form, proportion and in the minor details of construction may be resorted to without departing from the spirit or sacrificing any of the novel features of the invention.

Having thus described this invention, what is claimed is ll separating device of the class described comprising an inclined trough, the bottom of which is provided with a central longitudinal channel, the portions of said bottom on opposite sides of the channel being inclined upwardly toward the side walls of said trough, a spiral screw disposed in said channel and rotatably mounted in the end walls of said trough, a discharge spoutmounted in the upper portion of the lower end of said. trough, an additional spout mounted in the bottom of the trough adja cent the opposite end thereoi and connnunieating with said longitudinal channel, said latter trough being inclined downwardly toward its free end and provided with a screen covering, and a perforated water supply pipe extending transversely of the trough midway of its ends.

in testimony whereof hereunto affix my signature in the presence of two witnesses.
